After a steady diet of Mobil1 since I brought it home from the dealer, I've recently switched my 5.7L hemi over to Motorcraft 5W-20 (the recommended weight). I do mostly highway runs of about 50-60 miles a couple times a week. While I was under warranty, I stuck with the required 6000 mile interval, but I have switched to 7500 miles now that it's out of warranty.
What's the conventional BITOG wisdom on taking the Motorcraft synthetic blend to 10,000 miles?
Thanks in advance,
